Concord, Mass.
1901. 
Sept. 17
  Cloudy with S. to S.E. wind and rather heavy rain after 
11 A.M.
  The Ball's Hill woods were alive with Black-poll Warblers
early this morning. There were fifteen or twenty about the cabins
when I first came out & I saw or heard as many more
later in the day in other places. Indeed the sound of
their chirping calls to one another was hardly out of my
ears the whole forenoon.
  The thickets bordering the river banks at Birch Gate 
have been a favorite rendezvous for small birds of various
kinds the past few days. I found there this morning,
besides the omnipresent Black-polls, a Nashville Warbler,
a Red-eyed Vireo, two brown Thrashers, two or three Cat birds,
an Indigo Bird (in plain brown plumage) and a Song sparrow
while further on, in the woods at the south base of
Holden's Hill I heard the chip-churr of a Tanager repeated
a dozen times or more. 
  The Carolina Rails were even more numerous & noisy
in the side along the river at & below Beaver Dam Rapids
than they were last Saturday (15th). They uttered all their
different cries by turn - the ere, whinny, squeal, kep & cup.
  The men beat the Snipe grounds with dogs firing three shots
in all. Pat tells me that there has been a good deal of
firing on these meadows the past week.
  I spent most of yesterday in Boston. As I was
crossing the River about sunset on my return I saw a 
flock of 17 Chimney Swifts. They came from the north
and after circling a few times high in air over Ball's Hill
drifted off towards the S.W.
